Title: Improvements in gyro-compasses
IPC: G01C19/38
Filed: 1920-03-24
Abstract: 165,221. Gott, A. E. March 24, 1920. Gyroscopic compasses.-Relates to means for correcting for the errors which arise in compasses in which the directive element is not stabilized, in all directions when the ship on which the compass is mounted is rolling and pitching on an intercardinal course. According to the invention,. the plane passing through the centre of gravity of the gyroscope case and rotor in which the maximum moment of inertia of the case and rotor about an axis in this plane and passing through the centre of gravity occurs, is brought into the vertical plane containing one of the cardinal axes by suitable distribution of mass upon the gyroscope case. This cardinal plane is preferably the plane of rotation of the gyroscope. Several constructional forms of the invention are described. In the form shown in Fig. 9, pairs of masses 7, 9 are attached to the extremities of the horizontal and vertical axes 8, 10, of the casing 4, which is pivoted on the axis 8 in the ring 6. The masses can be adjusted about the said axes and secured in their adjusted positions. In the form shown in Figs. 10 and 11, a frame 13 carrying masses 14, 15, adjustable along rods 16, 17 is attached to the axis 8 about which it is adjustable. Fig. 12 shows an arrangement in which masses 18, 19 are arranged so as to be both radially and circumferentially adjustable in relation to the axis of spin of the rotor. In a further modification the casing 4 is provided with sockets, which may be arranged parallel to the gyroscope axis, or horizontally or vertically at right-angles to this axis,. for the reception of the masses. Alternatively, the casing may be formed with cavities adapted to be charged with lead &c. The masses may be so arranged that the casing is dynamicallv balanced' about an axis parallel to but below the axis of spin so that the masses provide the pendulous factor for controlling the compass. The proper. distribution of the masses is determined by subjecting the compass to swinging tests.

In the form shown the movement of a reciprocating slide 3 is limited by stops 8, the appropriate stop being brought into action by the operation of an electromagnet. The slide 3 bears a cam 18 which cooperates with a roller on a transverse slide 15, bearing an electromagnet 29. At each movement of the slide 15 the electromagnet 29 is energized and moves forward the travelling bar 28 which is retained in position by a second electromagnet 30 when the electromagnet 29 is de-energized on the return stroke of slide 15. The ratio between the strokes of the slides 3 and 15 is varied by a screw head 26. All the moving parts are spring returned.
